Holley is proud to announce the all new plug and play Dual Sync Billet Distributor lineup, Holley EFI analog style gauges, and Gen III Hemi harnesses from Holley EFI.

Dual Sync Distributors

These high-quality distributors feature CNC machined billet aluminum construction that houses a pair of ultra-accurate Hall Effect sensors for both camshaft and crankshaft position to support sequential EFI operation. The Hall Effect sensor design provides precise timing control and noise immunity. The precision machined shutter wheel ensures a rock solid RPM signal beyond 8,000 RPM. With a simple plug and play installation and integrated LEDs for easy setup, these units will have your show car or race car up and running in no time with Holley EFI or other aftermarket EFI systems.

Holley's analog style gauges are designed specifically for use with Holley EFI systems. This includes all Terminator, HP, Dominator, and Sniper ECUs, allowing them to be installed in any vehicle with Holley EFI. The CAN communication allows the gauges to daisy chain using the included stereo cables, which makes installation quick and clean. The required gauge module allows plug and play communication between the ECU and gauges via a one-wire ECU connection. All gauges fit 2-1/16" mounting holes. They are also compatible with all Holley EFI touchscreens, dashes, handheld tuners, and other CAN devices, making them great for users looking to install a combination of needle gauges and LCD accessories.
